Synchronization Failed - Termporary Issue

For about half an hour, I was getting "The synchronization failed. Do you want to try again?" every time the sync fires off. I've been using the tool for about a month now without issue. The output on the Sync tab shows this:

I don't know where to find the OGcalsync.log. I did a search of my whole C: drive and came up empty. The application appears to be installed in a sub-folder deep within my _%USERNAME%\AppData\Local_ folder, but there's no .log files there.

While I was typing this up, it seems to have resolved the issue. Perhaps it was just a network glitch or something, but I figured I'd post it just in case there was actually something going on with the application.
